Roller bearings: wear-resistant transmission components for heavy-duty guidance

Roller bearings are a special type of bearing designed for rolling contact guides. The core feature is that the outer ring adopts a thick-walled arc surface or cylindrical surface structure, which can directly roll in contact with contact surfaces such as guide rails and rails. It has radial load-bearing, axial guidance and impact resistance properties. It is suitable for scenarios such as conveying equipment, hoisting machinery, and metallurgical rolling mills that require heavy loads to move along fixed trajectories. It is a key guide component in the "moving heavy load" scenario in the industrial field.

From a structural point of view, this type of bearing usually consists of five parts: "thick-walled outer ring, inner ring, rolling elements (cylindrical rollers/spherical rollers), cage, and seals". The core design highlight is the thick-walled outer ring: the outer ring wall thickness is thicker than that of ordinary shafts The bearing height is 2-3 times, and the outer circle is mostly arc surface (suitable for arc guide rails) or precision cylindrical surface (suitable for linear guide rails). The surface is quenched and ground, with a hardness of HRC60-62, and the wear resistance is far superior to that of ordinary bearing outer rings. ; The rolling elements are selected according to the load type. The cylindrical roller type (such as the NATR series) focuses on radial heavy loads, while the spherical roller type (such as the RNA series) has a slight self-aligning ability and can compensate for the guide rail installation deviation; the cage is mostly made of steel plate stamping or brass to ensure the rolling elements are evenly distributed; most models come with double-sided seals (such as the 2RS type), with a protection level of IP54, which can block the intrusion of dust, iron filings and coolant, and reduce grease leakage.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
